T0' all whom t may concern:

Be it known that I, PATRICK KANE, a citizen of the United States,residing at Bruno, in the county of Pine and State of Minnesota, haveinvented new and useful Improvements in Loaders, of which the followingis a specification.

This invention relates to loaders and it consists in the novel featureshereinafter described and claimed.

An object of the invention is to provide a loader of simple and durablestructure which may be conveniently used for loading ties upon railwaycars or similar vehicles and for removing the ties from the cars orvehicle.

With this object in view the loader com* prises masts which arepositioned vertically upon the ground and spaced from each other. Cabletracks are trained over the upper ends of the masts and suitably securedat their ends. A cable is connected at its end portions with the mastsand is located below the cable tracks. A traveler is mounted formovement along the cable tracks and a carriage is suspended from thetraveler. An engine is mounted upon the carriage. Shafts are journaledupon the carriage and means are provided for rotating either of the lastmentioned shafts from the shaft of the engine. One of the shafts whichis journaled upon the carriage is provided with a drum around which theintermediate portion of the second mentioned cable is wound. A hoistingcable is arranged to wind upon the drum of the other shaft and the saidhoisting cable may be trained around the pulleys of suitable blocks oneof which is attached to the carriage and the other block may sustain theweight of the load.

In the accompanying drawing Figure 1 is a side elevation of the loader;

Fig. 2 is a top plan View of the same;

Fig. 3 is a bottom plan view, and

Fig. 4 is a longitudinal sectional view.

The loader comprises masts 1 which are positioned vertically upon thesurface of the ground. Track cables 2 are trained over the upper ends ofthe masts 1 and the said cables are extended parallel with relation toeach other.` A cable 3 is connected at its ends with the masts 1. Atraveler 4 is arranged for movement along the cables 3. A carriage 5 issupported from the traveler 4 by means of hangers 6 which may be in theform of rods or other suitable structure.

An engine is mounted upon the carriage 5 and its shaft 7 is provided inthe vicinity of one end with a fly wheel or pulley 8. A friction pulley9 is mounted upon the shaft 7 and the said pulley may be composed ofpaper or-any other suitable material. A shift lever 10 is pivoted uponthe carriage 1 and may be moved to shift the pulley 9 laterally. Apropelling shaft 12 is journaled upon the carriage 5 and is provided ata point between its ends with a drum 13. The drum 13 is provided with aconcaved periphery. A disk 14 is mounted upon the shaft 12 and islocated opposite a friction pulley 9.

A hoisting shaft 15 is journaled for rotation upon the carriage 5 and adrum 16 is mounted upon the intermediate portion of the hoisting shaft15. A disk 17 is mounted upon the shaft 15 and is located opposite thefriction pulley 9.

A cable 18 is arranged to wind upon the drum 13 and the intermediateportion of the said cable is trained around the pulley of a block 19 towhich the load, to be lifted,

is attached. Ablock 2O is carried by the car riage 5 and theintermediate portion of the cable 18 is trained around the pulley of theblock 20. The other end of the cable 18 is attached to the block 19 asbest shown in Fig. 1 of the drawing. Brake levers 21 are pivoted uponthe carriage 5 and the said levers carry at their undersides shoes 22which may be brought into frictional contact with the peripheries of thepulleys 14 and 17. Rack bars 23 are mounted upon the carriage adjacentthe free ends of the levers 21 and the levers may be provided with pawlsfor engaging the said rack bars whereby the said levers will be held atadjusted positions.

It is apparent that when the shaft 15 is vheld at a state of rest by theapplication of wound about the drum 13. In view of the fact that thedrum 13 is provided with a concaved periphery the coil in the cable 13will be held approximately midway between the ends of the drum 13.

When the carriage 5 has moved to a Clesired point along the cable tracksthe lever 10 is swung whereby the disk 9 is moved out of engagement withthe disk 11 and the shaft 2 is held against rotation by the applicationof the shoe 12 carried by the lever 21 to the periphery of the disk 14.Vhen the disk 9 is moved into engagement with the disk 17 the shaft 15is rotated whereby the cable 18 is wound upon the disk 16 andconsequently any load which is attached to the block 19 maybe raised orlowered according to the direction in which the shaft 15 rotates.

F rom the foregoing description taken in conjunction with theaccompanying drawing it will be seen that a loader of simple and durablestructure is provided and that the same may be used to advantage forloading material upon railway cars or for removing material therefrom. t

Having described the invention what 1s claimed is In a loadingapparatus, a carriage, an engine mounted on said carriage, a frictionpulley on the shaft of said engine, a pair of shafts journaled in saidcarriage at the sides of and in spaced parallel relation to said engineshaft, friction pulleys on said second named shaftsin position to beengaged selectively by said first named friction pulley, means forshifting said. first named pulley into engagement with either of saidsecond named pulleys, a block supported above said first named pulley,levers pivoted upon said block, brake shoes on saidv levers engageablewith said second named pulleys and means for holding said levers inselected positions for controlling or preventing rotation of said drums.

In testimony whereof I affix my signature.

PATRICK KANE.
